Tentative study of stresses in a rail by photoelastic and extensometer measurements

Residual stresses in the rail (cont.). Study of the workhardened zone

Composition of the different stress conditions in the wheel/rail contact zone. Development of a new fatigue criterion

Experimental studies: 1. Workhardening speed with the EMS 60 machine (additional measurements) 2. Residual stresses in hardgrade steel rails (additional measure ments) 3. Checking of fatigue criterion proposed by Mr. DANG VAN

Calculation of complex stress cycles in the rail subjected to rolling loads Assessment of the danger of damage (continued)
